Nephropathy induced by contrast medium in an hispanic population after coronary angiography.

Unlabelled: Contrast medium-induced nephropathy (CIN) is regarded as one of the most important complications after intravascular administration of radiographic contrast media and the third most common cause of hospital-acquired acute kidney injury. Contrast-induced nephropathy may develop in up to10% of patient with normal renal function but may be as high 25% in patient with risk factors.

Methods: A total of 192 medical records were obtained, in which 55 patient were eligible by our inclusion and exclusion criteria.

Results: A total four cases of CIN (7%) was identified and all were considered high-risk patients. In the patients that developed CIN only 50% received preventive IV hydration therapy in accordance to guidelines of the Contrast-Induced Nephropathy Consensus Panel. In 51 cases CIN was absent (93%). In the absent CIN group 22 were considered high-risk patients (43%) and 29 patients were low risk (57%). In the high-risk group with absent CIN, 77% received preventive IV hydration.

Conclusion: Study didn't show diabetes as a direct contributory factor for CIN development, but glycemia was not properly stratified. Screening and preventive strategies were not diligently complied in our institution, so there is a great need to incorporate a protocol in our institution in accordance to published guidelines.
